Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a micro-pressure oxygen chamber. Background Technology

[0002] As a medical device that promotes human health by providing an oxygen-rich environment at a pressure slightly higher than atmospheric pressure, the microbarotropic oxygen chamber has been widely used in fields such as rehabilitation medicine, sports recovery, and high-altitude acclimatization. By increasing environmental pressure and oxygen concentration, the microbarotropic oxygen chamber accelerates blood oxygen diffusion, improves tissue metabolism, and thus relieves fatigue and promotes wound repair.

[0003] The functional principle of microbarotherapy is to place a person in a specific microbarotherapy chamber, where the air pressure inside the chamber is higher than the local air pressure by a certain value. Inhaling pure oxygen at a concentration of no less than 90% greatly increases the partial pressure of oxygen in the alveoli, improves blood oxygen tension, increases blood oxygen content and oxygen diffusion, effectively improving the person's hypoxia level and reaching or exceeding the critical oxygen tension required for wound healing. This promotes angiogenesis and wound repair. However, most existing microbarotherapy chambers are small, soft structures whose structure and comfort are insufficient for wound repair purposes. Currently, there are a few large microbarotherapy chambers on the market, but they are bulky, difficult to disassemble and move, and their oxygen concentration is unstable. Too low an oxygen concentration will not achieve wound repair, while too high an oxygen concentration can easily lead to safety accidents. Utility Model Content

[0028] See Figure 1 A micro-pressure oxygen chamber includes a chamber body 1, an oxygen generator 7, an oxygen inhalation terminal, a pressure control device, a detection unit, and a control unit.

[0029] The oxygen inhalation terminal and detection unit are installed in the cabin 1. The oxygen inhalation terminal is connected to the oxygen end of the oxygen generator 7 through a pipeline. The oxygen inhalation terminal is used to output oxygen at different flow rates, thereby forming two oxygen inhalation modes: diffused and / or saturated.

[0030] The pressure control device includes a pressurization device, a pressurization line, and a pressure reduction line.

[0031] One end of the pressurization pipeline is connected to the pressurization device, and the other end of the pressurization pipeline is connected to the cabin 1. The nitrogen end of the oxygen generator 7 is connected to the pressurization device. One end of the depressurization pipeline is connected to the cabin, and the other end is connected to the depressurization valve.

[0032] This detection device is used to measure the temperature, humidity, and humidity parameters of the cabin.

[0033] The control unit is connected to the oxygen generator 7, the pressurization device and the pressure reducing valve respectively. The control unit controls the working status of the oxygen generator 7, the pressurization device and the pressure reducing valve according to the temperature, humidity and humidity parameters of the cabin.

[0034] In some embodiments, the cabin includes a cabin body and a door, and the cabin body is provided with at least one observation window 4, through which staff can directly observe the status of the personnel using the cabin body 1 to ensure the safety of the personnel.

[0035] The observation window is preferably made of pressure-resistant glass.

[0036] To improve user comfort and alleviate muscle fatigue, allowing users to achieve deep relaxation, the cabin is equipped with a massage chair 8. This massage chair is preferably a multi-functional massage chair. Users sit on the multi-functional massage chair while receiving oxygen, and the massage chair massages the patient's neck, back, waist, and limbs, helping the person in the cabin to relax and eliminate fatigue.

[0037] The cabin wall panels include an outer pressure plate 2 and an inner decorative plate 3, as well as an insulation layer filled between the pressure plate 2 and the decorative plate 3, which is insulation cotton.

[0038] Furthermore, in order to improve the installation efficiency of the cabin, the cabin is a splicing structure, including a bottom plate, a top plate and side plates. The side plates include multiple splicing plates, which are spliced ​​together end to end along the circumference of the wall. A sealing strip is set between two adjacent splicing plates to ensure the sealing performance of the cabin.

[0039] During the assembly of the cabin, the base plate is first installed on the foundation, and then multiple splicing plates are spliced ​​together at the edges of the base plate. Insulation cotton is laid on the inner wall of the splicing plates, and interior panels are laid on the surface of the insulation layer. The interior panels are connected to the pressure plate by adhesive or bolts. Finally, the top plate is installed on the top of the wall panels to form a complete cabin.

[0040] It should be noted that during installation, sealing strips need to be filled at each joint to ensure the overall sealing performance of the cabin and maintain it under slight pressure. Additionally, the top and bottom panels can also utilize a spliced ​​structure, identical to that of the wall panels, to reduce the difficulty of transporting the cabin.

[0041] For example, the hull is made of carbon steel and uses flange connections for easy disassembly, movement, and maintenance. The hull consists of a pressure-bearing layer, a decorative layer, observation windows, hatches, and various through-hole pipes. The hull is detachable and movable.

[0042] In some embodiments, the oxygen generator 7 is a molecular sieve pressure swing adsorption (PSA) oxygen generator or a membrane separation oxygen generator. During operation, the oxygen generator 7 separates nitrogen from the air to form oxygen and nitrogen. The control terminal of the oxygen generator 7 is connected to the control unit 10, and the oxygen output terminal of the oxygen generator 7 is connected to the oxygen inhalation terminal. The oxygen generated by the oxygen generator 7 is pressurized and output through pipelines to the oxygen inhalation terminal to provide users with oxygen at different flow rates, forming two oxygen supply modes: diffused and saturated. The nitrogen output terminal of the oxygen generator 7 is connected to a pressurization device, which inputs nitrogen into the cabin to regulate the oxygen concentration in the cabin and prevent the oxygen concentration in the cabin from exceeding the safe value and causing danger.

[0043] The oxygen inhalation terminal includes a nasal cannula and a saturation oxygen inhalation mask. The oxygen output pipeline of the oxygen generator 7 is provided with two branches. One branch is connected to the nasal cannula through a flow controller, and the other branch is connected to the saturation oxygen inhalation mask. The flow controller is connected to the control unit 10.

[0044] Nasal cannulas deliver oxygen generated by an oxygen concentrator directly to the user's nasal cavity via tubing. The oxygen concentrator produces a high concentration of oxygen, which flows from its output end into the nasal cannula's tubing. When using a nasal cannula for low-flow oxygen inhalation, the oxygen enters the nasal cavity at a relatively slow rate. At this time, the oxygen mixes thoroughly with the surrounding air within the nasal cavity, and with breathing, it gradually diffuses into the respiratory tract and lungs. This low-flow oxygen supply method can increase the oxygen concentration of inhaled air within a certain range, placing the user in a relatively oxygen-rich environment, achieving the effect of diffused oxygen supply. For example, in some high-altitude areas, residents may use nasal cannulas for low-flow oxygen inhalation to alleviate the hypoxia symptoms caused by altitude sickness.

[0045] The saturation oxygen mask mainly consists of the mask body, securing straps, oxygen inlet, and exhaust vent. Its working principle is as follows: First, the securing straps tightly fasten the mask to the user's face, creating a relatively sealed space. Oxygen generated by the oxygen generator enters the mask through the oxygen inlet. The mask's airtightness is crucial; it prevents large amounts of outside air from entering the mask while minimizing oxygen leakage. Thus, when oxygen enters the mask, it accumulates inside, creating a high-concentration oxygen environment. The user breathes in this sealed environment, primarily inhaling the high-concentration oxygen from within the mask, significantly increasing the inhaled oxygen concentration. The exhaust vent of the saturation oxygen mask is connected to the outside of the chamber via a pipe, allowing the user's exhaled oxygen and carbon dioxide to be discharged outside the chamber, preventing any impact on the oxygen concentration inside.

[0046] The main advantage of a saturation oxygen mask is its ability to provide a high concentration of saturated oxygen. By increasing the oxygen output flow rate of the oxygen concentrator, a large amount of oxygen rapidly fills the mask, achieving a high oxygen concentration within it. During breathing, the user inhales almost pure oxygen or a high concentration of oxygen, quickly increasing blood oxygen saturation and meeting the body's oxygen needs. For example, in emergency situations and intensive care settings, saturation oxygen masks are often used to provide patients with high-concentration oxygen therapy. Simultaneously, the vents on the mask allow for the expulsion of waste gases such as carbon dioxide, ensuring normal gas exchange within the mask.

[0047] In some embodiments, the pressure control device functions to control the pressure and oxygen concentration of the chamber 1.

[0048] The booster device is an air compressor. The control terminal of the air compressor is connected to the control unit 10. The output terminal of the air compressor is connected through the booster device chamber. The air compressor uses a boosting method to input air into the chamber, so that the chamber is in a low-pressure state. The control unit 10 controls the working state of the air compressor according to the pressure of the chamber.

[0049] For example, the pressurization device includes two parallel air compressors, one of which inputs air into the cabin, and the other air compressor is connected to the nitrogen end of the oxygen generator. During the diffusion oxygen inhalation process, the oxygen exhaled by the user will cause the oxygen concentration in the cabin to increase. Then, nitrogen is input into the cabin through the air compressor to quickly adjust the oxygen concentration in the cabin and avoid the problem of excessive oxygen concentration in the cabin causing danger.

[0050] Furthermore, during the process of the compressed air generated by the air compressor being input into the cabin, the compressed air will produce noise through the air inlet at the top of the wall, which will cause discomfort to the people inside the cabin. Therefore, a pressurization silencer is installed at the air inlet of the cabin, and the pressurization pipeline is connected to the pressurization silencer to reduce the noise of the compressed air input into the cabin.

[0051] This pressurized silencer, also known as a booster silencer or compressed air silencer, works by changing airflow dynamics, absorbing sound energy, or interfering with sound wave propagation to reduce noise.

[0052] The pressurized silencer can be a resistive silencer, a reactive silencer, a resistive composite silencer, or a micro-perforated plate silencer.

[0053] For example, a resistive silencer includes a housing and a layer of sound-absorbing material (glass wool, slag wool) disposed inside it. The surface of the sound-absorbing material layer is provided with a protective layer, which is made of materials such as metal mesh or fiberglass cloth, which can both protect the sound-absorbing material and ensure the smooth passage of airflow.

[0054] In some embodiments, the pressure-reducing pipeline includes an air outlet, a pressure-reducing silencer, a pressure-reducing pipeline, and a pressure-reducing valve.

[0055] The air outlet is located at the bottom of the wall panel and is diagonally positioned to create a circulating convection of air inside the cabin. The pressure reducing silencer is located at the air outlet and embedded in the wall panel. The pressure reducing silencer is connected to the pressure reducing valve through a pressure reducing pipeline. The pressure reducing valve is connected to the control unit 10. The control unit 10 controls the working state of the pressure reducing valve according to the pressure in the cabin to reduce the pressure in the cabin.

[0056] A pressure-reducing silencer reduces noise generated by throttling, expansion, or turbulence while lowering gas pressure. A pressure-reducing silencer is a gas pressure-reducing silencer.

[0057] During operation, the pressure of the chamber is collected. When the pressure of the chamber exceeds the threshold, the control unit controls the pressure reducing valve to start, so as to reduce the pressure in the pressure chamber and also reduce the oxygen concentration in the chamber.

[0058] In some embodiments, the cabin is also equipped with a temperature and humidity control device, such as an air conditioner, to control the temperature and humidity of the cabin. The air conditioner's control terminal is connected to the control unit. The air conditioner consists of an indoor unit, an outdoor unit, a water tank, and a circulating water pump. Antifreeze is used as the refrigerant to enable energy transfer between the inside and outside of the cabin.

[0059] In some embodiments, the detection unit includes an oxygen concentration sensor, a temperature and humidity sensor, and a pressure sensor. The oxygen concentration sensor measures the oxygen concentration in the chamber, the temperature and humidity sensor measures the temperature and humidity of the chamber, and the pressure sensor measures the pressure of the chamber. The oxygen concentration sensor, temperature and humidity sensor, and pressure sensor are all connected to the control unit. The control unit controls the operating status of the corresponding devices based on the collected data to control the operating status of the chamber. When the oxygen concentration sensor detects that the oxygen concentration in the chamber exceeds a set threshold, the control unit stops the oxygen generator from working. For example, if the oxygen concentration threshold is greater than 23%, the oxygen generator stops working.

[0060] The control unit is a PLC controller, which is connected to a human-machine interface (HMI). The HMI includes an external HMI 11 and an internal HMI 12. The external HMI 11 is located on the outside of the cabin, for example, on the outer wall, while the internal HMI 12 is located inside the cabin. The HMI is used to manually input the cabin's operating conditions, set working parameters for the PLC controller, issue working instructions, and display parameters such as pressure, oxygen concentration, temperature, humidity, air compressor, oxygen generator, and pressure reducing valve transmitted from the PLC controller. The HMI and the PLC are connected via electrical wiring. The HMI can call the air compressor, oxygen generator, and pressure reducing valve in real time to achieve stable pressurization, pressure stabilization, pressure reduction, and ventilation according to the set scheme.

[0061] In some embodiments, a lighting assembly 5 is provided on the top of the cabin, which consists of an ambient light and a main light. The main light enables brightness adjustment, and the ambient light enables color adjustment.

[0062] The cabin is equipped with an external emergency exhaust valve and an internal emergency exhaust valve, respectively. In case of an emergency, personnel inside and outside the cabin can open these valves to quickly release pressure and ensure that personnel can exit the cabin quickly.

[0063] The cabin is also equipped with a safety valve, which serves as a cabin protection device. If the control system malfunctions and causes the cabin pressure to rise beyond the safe range, the safety valve will automatically open to release pressure and ensure the safety of the cabin.

[0064] The cabin is also equipped with a sound module, which is a Bluetooth multimedia system that can connect to Bluetooth to play guiding music and relaxation instructions to help people inside the cabin quickly achieve a relaxed state.

[0065] In some embodiments, the air compressor and oxygen generator are installed in an equipment compartment, which includes an inner layer and an outer layer, with an interlayer between the inner and outer layers. This interlayer serves as a heat dissipation layer, with heat dissipation holes on both the inner and outer sides. A cooling fan is installed in the heat dissipation holes on the outer layer to extract hot air from the equipment compartment. This allows the temperature generated during the operation of the air compressor and oxygen generator to be discharged to the outside through the interlayer. The double-layer structure of the equipment compartment also reduces the operating noise of the equipment, making the micro-pressure oxygen chamber suitable for use in environments requiring a relatively quiet environment (such as teaching environments).

[0066] The oxygen concentrator, air compressor, and outdoor air conditioning unit serve as power equipment. These power units are supplied with leakage current protection to ensure the safety of personnel and equipment. The equipment inside the cabin and the control equipment outside the cabin are triple-protected by leakage current protectors, fuses, and isolation transformers to ensure the safety of personnel and equipment. The equipment inside the cabin and the control equipment outside the cabin are connected after the isolation transformer. Furthermore, each electrical device undergoes a functional test under a pressure of 0.15 MPa before selection to ensure safe operation under a pressure of 0.04 MPa. The equipment inside the cabin and the control equipment outside the cabin include the massage chair, indoor air conditioning unit, lighting components, music components, human-machine interface, and various electrically operated valves.

[0067] This application provides a micro-pressure oxygen chamber, including a chamber body and an oxygen generator, pressure control device, detection unit and control unit connected thereto. The chamber body forms a relative pressure environment 0.1-0.4 times higher than atmospheric pressure, and provides two oxygen inhalation methods, diffused oxygen and saturated oxygen, through an oxygen inhalation terminal, to realize the training and rehabilitation tasks of the user.

[0068] The above content is only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed in this utility model shall fall within the scope of protection of the claims of this utility model.
